Application i'lled March 22, 1904. Serial No. 199,378.

To all wtont it 71mg/ concern:

Be it known that I, RICHARD NUssBEcK, a citizen of the United States, residing' at Chicago, in the county of Cook, State of Illinois, have invented certain new and useful Improvements in Latches, of which the following is a specification.

In the drawings, Figure l is an elevation of the interior face of a door mounted in a 'frame and embodying my invention, parts being broken away. Fig. 2 is a section of the same on the line 2 2, Fig'. 1, parts being in elevation. Fig. 3 is a view similar to Fig. 1, illustrating my invention embodied in double doors. Fig. 4L is a side elevation of the operating-lever.

5 represents a suitable door-frame in which the door 6 is hung by means of the hinges 7,

said door being of any approved style. While I have not shown a knob attached to the door, it is of course obvious that one may be employed in connection with the lock, as its presence will not prevent the operation thereof.

8 is a shaft the ends of which are reduced, as at 9, to form journals, said journals being' journaled in angle-brackets 10, secured to the door by means of screw 11 or otherwise, as may be found most convenient. The horizontal member of the angle-bracket is provided with an opening forming a bearing in which the journal of the shaft 8 is journaled.

12, 13, and 1A are levers secured to the shaft 8, but spaced apart, as clearly shown in Fig. 1, said lever extending substantially the width of the door. These levers are preferably of angle-iron, as more clearly shown in Fig. 4.

The lever 13 is provided with a depending boss 1li, the under face of which is provided with teeth 15 and a recess 16, in which one end of the chain 17 is secured, `the links near lthe immediate end of the chain passing over and engaging' with the teeth 15, thereby relieving the pin 17, which holds the chain in the recess 16, of undue strain. 18 is a lock of approved type having a locking-bolt 19, to which is secured, by means of a pin 20, the other end of the chain 17, as clearly seen in the views.

Each of the arms 12, 13, and 14 is provided with chains 21, one end of which is secured to the door, whereby the movement of the arms from the door is limited.

The lock 18 may be of a type whereby it can be operated from the exterior by means of a suitable key 22; but of course it is understood that the locking-bolt 19 is free to be withdrawn independent of said key from the interior.

It will be seen from Fig. 2 that the several parts embodying my invention extend some distance from the inner face of the door, and in order to make the construction sightly I provide a covering' 23, which is secured in a suitable manner to the levers on the doorand forms a push-board.

is a fiat or other suitable spring interposed between the door and the under face of the levers 12, 13, and 14, as more clearly shown in Fig. 2, wherein the spring is shown as of U-shaped construction. l

The particular object of my invention is to provide a door which can be readily opened from the interior of a building in an emergency without the use of a key, and should such an emergency occur the pressure of the body upon any part of the push-board, which is of sheet-iron, will revolve the shaft 8, thereby winding the chain 17 upon the depending boss 1A, thus withdrawing the locking-bolt 19 from its keeper and permitting the door to be swung open, thus providing ready exit.

In Fig. 3 the only difference in showing from Fig. 1 is that I have illustrated double doors and positioned the locks at the top and bottom thereof, thus necessitating the use of groove-rollers 26, over which the chains 17 move, said rollers being mounted on suitable journals 27.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is4

1. The combination with a swinging door, of a bolt, a lever pivoted near the. hinged edge of the door on an axis parallel to the axis of the door and extending across the door to a point adjacent the opposite edge, and a chain connected to the lever near its axis and extending beneath the lever and connected to the bolt.

".lfhe combination with zi door, of :t lever pivoted thereto., a,V key-look secured to Seid door, e holt of whieh is free to net independent o'r' the key, and nien-ns connecting the pivoted end of seid leveil with the bolt ol' Seid lock.

The combination with e door having e enitzihle look, el n. Shaft journnled in :in upright position en seid door, levers extending' Vl'roln :seid shaft und keyed thereto et one end, end e ehitin connecting the keyed end oi' one of seid levers to the holt ot' sind leek.

4. The combination with the door having zi snitehle look, of e shaft journeled thereon in en upright position, leverel keyed et one end to eeid:'-;l1nlt,inezn1e limiting the outward movements of said levers from the door, chain eonneetingthe keyed end of one of S21-id levers to the holt of the leek, and :t spring interposed between the door lind said levers.

5. 'lhe combination with e door having a suitable loek, ol' :i lever pivoted at one end thereto, e boss integral with the. pivoted end of seid lever provided with teeth, and a Chain eoi'ineetingsziid boss and the holt of Seid lock,

the teeth of said boss engaging the linke ot' seid chain.

6. The combination with the Swinging door, of a lever pivoted on a. vertical exis to the door neer the hinge edge thereof, e holt for the door neer its Swinging edge, and a chain connected to the lever neer its pivot land lto the holt.

7. The combination with theswinging door, a. bolt Ytor the top ot' the door near its ewinging edge, a bolt for the bottoni of the door near its swinging edge, oi e lever pivoted on a vertical exis to the door near the hinged edge thereof, and connections between the lever neer its pivot and both bolts to Cause both bolts to be Withdrawn simultaneously upon pressure being applied to the free end of the lever.
